Open-Ended Belts in Inch Profiles - XL, L, H, XH

Open-ended polyurethane timing belts in inch profiles have been designed to comply to every need of the design engineer in linear motion, power transmission and in conveying applications where precise synchronisation is needed. Timing belts are manufactured with the body in thermoplastic polyurethane with excellent wear resistance and with high tensile strength steel cords. A special polyamide fabric on the tooth (on request) reduces the coefficient of friction, improves the tooth engagement and reduces noise.


Profiles and dimension:


Areas of application:
Polyurethane timing belts can be used in all areas, from miniature drives, high precision positioning and sorting machines, small handheld machines to high-performance drives for building and woodworking machines.

Mechanical properties:
  • Excellent dimensional stability
  • High abrasion resistance 
  • Low pretension and shaft load 
  • Maintenance free
  • High linear and angular positioning precision 
  • High efficiency
Chemical properties:
  • High resistance to: hydrolysis, ozone, UVA, ageing, oils, greases and fats and gasoline
  • Good resistance to acids
  • Working temperatures range -10°C +80°C (peaks up to 110°C)
    For very low temperature special compound material is available on request.
  • Silicon free production
